Description

A three panel mosaic of the region including Orion on the south end, imaged over multiple nights. Nikon 85mm f/1.4 lens, used at f/4.

Starting from the far South (left), there is Barnard's Loop. I used to think of this as a faint object. No more, it now seems somewhat "bright". The Orion Nebula is completely saturated and the
Horsehead is just visible. Moving North is the VERY bright Betelgeuse, and the huge Sharpless 2-264 below it. Straight above at the very top of the frame is the familiar Rosette, Monoceros Loop and Cone Nebula.

Moving from there diagonally to the bottom right corner there are in succession a number of planetary nebulae, the bright NGC2174, and IC443 to the upper right from it. Continuing to the lower right
corner is M35 and then the delicate filaments of Sh2-240. Finally M36 and M38 in the bottom right corner. The Crab (M1) barely shows as a diffuse star at this resolution--near the bottom, right of center, not even easy to find.
